Question 3 :
A body of mass <em>m</em> slides down an incline and reaches the bottom with a velocity <em>v</em>. If the same mass was in the form of a ring which rolls down this incline, the velocity of the ring at the bottom would have been
Question 4 :
Generally the mass of fly wheel is concentrated in its rim. Why?
Question 5 :
A recording disc rotates steadily at 45 rev/min on a table. When a small mass of 0.02 kg is dropped gently on the disc at a distance of 0.04 m from its axis and stucks to the disc, the rate of revolution falls to 36 rev/min. The moment of inertia of the disc about its centre is
